If you own a rental property in Tunbridge Wells — whether it is a Victorian terrace near the Pantiles, an Edwardian semi in St James’s, or a period conversion in Calverley Park — the clock is ticking on one of the most significant compliance deadlines the private rental sector has seen in years.
The government’s proposed minimum Energy Performance Certificate (EPC) standard of Band C for new tenancies is expected to come into force by 2028. For landlords across the TN1 to TN4 postcode areas, this is not a distant concern. It is an immediate planning priority.
At Belvoir Tunbridge Wells, we are already helping local landlords understand what these changes mean for their specific properties — and how to act now before costs rise and options narrow.
What the 2028 EPC changes mean for landlords
Under the current rules, rental properties in England must hold a minimum EPC rating of Band E. The proposed uplift to Band C represents a substantial leap for many older properties, and Tunbridge Wells has a particularly high concentration of pre-1919 housing stock.
The proposed timeline is as follows: Band C will be required for all new tenancies from 2028, with all existing tenancies expected to comply by 2030. While the legislation has not yet been fully enacted, the direction of travel is clear — and landlords who wait until the deadline will face a very crowded market for contractors, higher installation costs, and the very real risk of void periods.
Failing to comply could ultimately render a property unlettable. That is not a risk any landlord should be taking lightly.
Why Tunbridge Wells properties face unique challenges
Royal Tunbridge Wells is renowned for its beautiful Georgian, Victorian, and Edwardian architecture. Streets around Calverley Park, the Pantiles conservation area, and St James’s are lined with period properties that are genuinely characterful — but often thermally inefficient by modern standards.
These homes were built long before cavity walls, loft insulation, and double glazing became standard. Many feature solid stone or brick walls, single-glazed sash windows, and older heating systems that are simply not compatible with current energy efficiency expectations.
Solid wall insulation: The big challenge for period homes
Unlike modern homes with cavity walls, many Victorian and Edwardian properties in Tunbridge Wells have solid walls. Cavity wall insulation — one of the cheapest and most effective upgrades — is simply not an option for these buildings.
Instead, landlords must consider either internal wall insulation (which reduces room size) or external wall insulation (which can affect the appearance of the property). In conservation areas such as the Pantiles, external insulation may require planning permission or may not be permitted at all.
This makes early engagement with a qualified retrofit assessor absolutely essential.
Heat pump suitability in older properties
Air-source and ground-source heat pumps are increasingly promoted as low-carbon alternatives to gas boilers. However, they are not universally suitable — particularly in older, draughty properties that have not been properly insulated first.
Heat pumps work most efficiently in well-insulated homes with underfloor heating or oversized radiators. Before investing in a heat pump for a period property in TN1 or TN2, landlords should commission a full suitability assessment. Installing one prematurely — without addressing the building fabric first — can result in higher energy bills for tenants and a poor EPC outcome.
Financial support available to Tunbridge Wells landlords
The good news is that financial support is available, and landlords across all portfolio sizes should be exploring these schemes now.
The Boiler Upgrade Scheme
The Boiler Upgrade Scheme (BUS) offers grants of up to £7,500 towards the cost of installing an air-source heat pump and up to £7,500 for a ground-source heat pump. This scheme is open to landlords as well as homeowners and can make a meaningful dent in upfront installation costs for eligible properties.
ECO4 grants
The Energy Company Obligation (ECO4) scheme is designed to help fund energy efficiency improvements for lower-income households. Landlords whose tenants are in receipt of certain benefits may be able to access ECO4 funding to cover insulation, heating upgrades, and other measures – at little or no cost to the landlords.
Whether you own one rental property or a portfolio of ten across Tunbridge Wells, it is worth checking eligibility. Belvoir Tunbridge Wells can point you in the right direction when it comes to assessing which schemes apply to your circumstances.
Practical steps landlords should take right now
With 2028 closer than it appears, here is a practical roadmap for landlords in the TN1 to TN4 area.
Step 1: Get a current EPC assessment
If your EPC was issued more than two years ago, commission a new one. The assessor will provide a list of recommended improvements and their estimated impact on the rating. This is your starting point.
Step 2: Commission a retrofit assessment
A retrofit assessor will evaluate your property’s specific construction type, heating system, and insulation status. For period properties in areas like St James’s or around the Pantiles, this specialist assessment is far more valuable than a standard EPC alone.
Step 3: Prioritise fabric-first improvements
Before investing in renewable heating technology, address the building fabric. Loft insulation, floor insulation, draught-proofing, and secondary or double glazing will all contribute to a higher EPC rating and reduce the load on any new heating system.
Step 4: Plan your budget and timeline
Contractor availability across Kent is already tightening as the 2028 deadline approaches. Landlords who plan and book work in 2026 and 2027 will have more choice, more competitive pricing, and far less stress than those who leave it to the last minute.
The cost of doing nothing
Properties that fail to meet Band C by 2028 will not legally be able to be let to new tenants. For landlords with mortgaged properties, this could also trigger issues with lenders who are increasingly scrutinising the energy efficiency of their buy-to-let portfolios.
Void periods are expensive. A property sitting empty for even one month while emergency upgrade works are carried out could cost a Tunbridge Wells landlord significantly more than the cost of planned, proactive improvements.
The earlier you act, the more control you have over costs, timelines, and outcomes.
